Product Description
Overview
Longitudinal seam tooling is divided into two ways: fixed longitudinal seam and lifting longitudinal seam. Longitudinal seam is convenient to realize the splicing function of cylinder and plate. Longitudinal seam series tooling is mainly used for the inner and outer longitudinal seam welding of medium and thin-walled cylinders, which can be equippedPAW,TIG,MIG/MAGwelding process. It is suitable for welding of carbon steel, stainless steel, titanium and its alloys, and is used for welding of food machinery, dyeing and finishing equipment, power switch busbar cylinder, medical machinery, special material chemical containers, power pipelines, air conditioning unit shells and other products. It can also increase the height of such tooling and increase safety protection devices according to the specific conditions of the workpiece. The welding process is reliable and efficient, and the entire welding longitudinal seam process is programmed and controlled.
Performance Characteristics
1Adopt key clamping method, good heat dissipation effect during welding, small workpiece deformation, and high welding quality
2Applicable thickness in0.4-12mmrange
3suitablePAW,TIG,MIG/MAGwelding process method
4can be welded carbon steel, stainless steel, aluminum alloy and other materials
5According to the structure of the workpiece, you can choose the standard series of tooling, but also according to the requirements of special custom
Yes. YP Petro accepts OEM/ODM orders based on customer drawings, technical specifications, or reverse-engineered samples. Our engineering team can confirm feasibility, recommend material upgrades, and provide quotations within 3-5 working days.
YP Petro manufactures power end components including extension rods, crossheads, crosshead pins, cross pin baffles, upper and lower guide plates, packing boxes, seal rings, and oil seal lips. We also supply crankshaft assemblies, gear sets, and connecting rods for major mud pump models.
In addition to cylinder liners, YP Petro supplies a complete range of fluid end parts, including pistons, piston rubber, valve bodies, valve seats, valve rubber, liner seals, cylinder head gaskets, valve cover seals, piston rods, clamp assemblies, valve covers, cylinder heads, flange heads, cylinder flanges, cylinder covers, and inhalation capsules. We also supply dampener diaphragms, pressure gauges, fittings, relief valves, and exhaust valves.
YP Petro cylinder liners are available in metric sizes from 100mm to 180mm and imperial sizes from 3" to 7.5" (including 3", 3.5", 4", 4.5", 5", 5.5", 6", 6.25", 6.5", 6.75", 7", 7.25", 7.5"). Custom sizes are available on request.
